Some provinces in Vietnam such as Binh Dinh province, one of the leading salt production provinces in Vietnam with an annual salt output of around 20K tons, have been setting up a collaboration model between enterprises and farmers. Salt companies are providing technologies and equipment for the farmers to produce salt more efficiently. In return, all of the salt will be bought by these companies. This not only helps increase the volume of salt produced but also improves the quality of salt, and consequently increase the price of salt in the market.
